Basically, what it comes down to is there are different ways of measuring the weight of the shipment. For product weight, if you ship a tonne, it counts as a tonne against the quota, but for the carcass weight, a conversion factor is applied. If you ship a tonne of boneless beef, the conversion factor is about 1.3. They count it as 1.3 tonnes even though you shipped one tonne. If it's bone-in, depending on what the percentage of the weight by bones is, it's a lower conversion factor.
Generally we do a 1.3 conversion.
